' Application fla'au ust 1 2, 1912. Serial No. 714,604.

, ing at Chicago, in the county'of Cook and State of Illinois, haveinvented'eertain new and useful Improvements in Vaporizers, of

which the following is a specification. I

The present invention relates toimprove ments in Vaporizers, and is,designed for use in connection with. gas operated engines ofvarioustypes.

The object of the invention is the provision of a vaporizer, attached,preferably to theexhaust pipe or tube of a gas engine and receiving heattherefrom to vaporize the crude, -or. other oil, fed to the vaporizer.-

In the practical application of my device for actual use in connectionwith the exhaust pipefrom the engine, I utilize means for regulating theflow of oil to the vaporizer where it is vaporized by the heat from theexhaust pipe in connection with-other mechanical means, and-.1 providefurther improved and novel features as .willbg evident from thefollowing specific'ation taken in connection with. the drawings.

In the accompanying drawings I have illustrated one complete example ofthe physical embodiment of my invention constructed according to thebest mode I have so far devised for the practical application of theprinciples.

Figure 1 is a vertical, longitudinal sec Fig. 2 is a transversesectional view of the vaporizer. Fig. 3 is'a bottom plan view of the oilspray or nozzle. Fig. 4 is a vertical longitudinal sectional View of theoil spray or nozzle.

In the preferred embodiment of m invention I employ the casing 1 whichorms a cylindrical chamber with closed ends, about the exhaust pipe 2, aportion of which is illustrated in the drawings and through which theexhaust from the engine passes, the gases of combustion serving to heatthe :interior of the chamber to atemperature sufliciently high in orderthat crude or other oil may be vaporized therein.

Within the casing and directly surroundingin close proximity the pipe 1is located a. wire gauze or screen 3 of foraminous material, while threeother screens 4, o, and 6 are located in the chamber adjacent theinterior walls of the cylindrical casing. The screen 3 is for theinfiowing oil and the screens 4 5, and 6, are for the purpose offiltering t eoutgoing gases.

Crude oil is fed, to the vaporizing cha nber-from a suit-ably locatedoil tank (not shown,) through the oil feed pipe 7. In

Fig; 1 it will be seen that the oil feed pipe 7 is" provided with areturn'bend 10" inside the casing or drum and a spraying nozzle 11 isinterposed in the pipe. This nozzle is formed with a dependingperforated cap 12 through which the oilis fed to the foraminous screen3. The return bend 10 permits the oil to become heated in its passage'through the drum before reaching the spray, and in this manner thevaporiza':

tion of the oil [is aidedby a preliminary heating A pluralityof'air'valves, as 18, areprovided in the drum 1 as air inlets to furnish5 fuel air -for;-'mixing"with the gases in the drum and-these valves areactuated by Suetion from the engine'as usual.

- The vapor or gas, w1th the air mingled" therewith passes through thefiltering screens 4,, 5, and 6' into the gas or fuel supply p'pe 14which is provided with'z'the usual regulating valve.

In Figv 1 an auxiliary gasolene supply.

tank is illustrated at 19 adapted to supply fuel through valve 20 to thefuel supply pipe. This supply is for use in starting the engine, as itwill of course be understood that the vaporizer illustrated willnot com7 The operation of the device is obvious..-

Crude or. other oil is fed through the oil pipe from a supply tank, intothe return bend in the drum. In its passage through the bend the oil isgiven a preliminary heating, and as it is sprayed through the perforated cap of the nozzle, the heat from the gases of combustion in theexhaust pipe vaporizes the oil. Air is admitted to the mence to vaporizethe inflowing oil until the e" 1. The combination with a heating mem berQf a drum surrounding the same and provided with closed ends, an oilinlet pipe to the drum, a foraminous screen surrounding said member fordistribution of oil, and

a similar screen adjacent the Walls of the drum forming a s ace forfiltered gas to pass to the outlet or the drum.

2'. A vaporizer comprising a heatin member, adrum incasing said memberan provided with oil inlet and gas outlet, a

foraminous screen surrounding the heating member for distribution ofoil, and a series memes the drum for filtering vapor in its passage tothe outlet.

3. The combination with a vaporizing drum having an oil inlet pipepassing therethrough with a return bend and provided with a spraynozzle, of a heating member within the drum, a foramino'us screeninclosing said member for distribution of oil, and a series of screensadjacent the walls of the drum forming a filtered gas space providedwith a gas outlet.

In testimony whereof I aifix my signature in presence of two Witnesses.
